Product Specification
RO Membrane Housing

Fiberglass tap and brackish water reverse osmosis membranes can be used interchangeably for the same applications. The fiberglass external piece within brackish RO membranes (rather than tape for tap water membranes) .
The strict requirements and diverse applications of the membrane separations industry has brought forth a new generation of corrosion resistant filament-wound fiber reinforced plastic (FRP) pressure vessels. These vessels are manufactured over precision mandrels, using a superior epoxy resin, resulting in the ultimate finished inside surface.
Tap and brackish water RO fiberglass membrane housings are ideally used in municipal water treatment, electronics manufacturing, industrial processing, food and beverage applications, automotive applications, and more.
Specification
◆ Made with high quality FRP with an advanced winding process.
◆ Designed for continuous, long-term use as housings for reverse osmosis.
◆ The intake rated trust cone reduces pressure drop at high speed flow rates. Its cone design guarantees high compression resistant properties.
◆ These vessels are available to house 1, 2, 3, 4, 5, and up to 6 eight inch membranes.
◆ The filament wound FRP shell is composed of continuous fiber glass impregnated with heated epoxy resin system.
◆ Allowable water PH range is 3-10 under normal operation conditions and 2-12 when vessel is periodically cleaned.

What is reverse osmosis membrane
- Reverse osmosis membrane is a film that is selective to the substance through which it is called a semi-permeable film, and generally can only pass through the solvent, but not through the solute, the film is called an ideal semi-permeable film. When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water) are placed on both sides of the semi-permeable film, the solvent in the dilute solution will naturally flow through the semi-permeable film and spontaneously to the concentrated solution side, this phenomenon is called osmosis.
- When osmosis reaches equilibrium, the liquid level on the concentrated solution side will be a certain height higher than that of the dilute solution, that is, a pressure difference is formed, and this pressure difference is the osmotic pressure. The size of the osmotic pressure depends on the inherent properties of the solution, that is, it is related to the type, concentration and temperature of the concentrated solution and has nothing to do with the properties of the semi-permeable film. If a pressure greater than the osmotic pressure is applied on the side of the concentrated solution, the flow direction of the solvent will be opposite to the original direction of penetration and begin to flow from the concentrated solution to the dilute solution side, this process is called reverse osmosis.
